Weather set to clear for Cup final

World Cup organisers said they were confident the final between France and Italy would go ahead in the Olympic Stadium in Berlin despite heavy storms in the German capital.

There is the possibility of rain and possibly a thunderstorm during the course of Sunday afternoon but it should be calmer by the time the final kicks off at 8:00pm local time (Monday 4:00am AEST), organising committee spokesman Gerd Graus said.

The temperature is forecast to be about 25 degrees Celsius.

"The match will be played tomorrow, we have no qualms about that," Mr Graus told a media briefing.

He added the pitch at the stadium had not been covered.

"There was a lot of rain, but the pitch is in the condition to absorb it," he said.

"There is no reason to cover it. In these kind of temperatures, covering the grass would actually have harmed it."

FIFA spokesman Markus Siegler said that in the event of a major storm during the match which put the safety of players and spectators at risk, the organisers would decide whether to delay the kick-off until later in the evening, or even until Monday (local time).

"In the worst case scenario it could be delayed until Monday," he said.

The German capital was hit by a major thunderstorm on Friday evening after days of uncustomary hot weather and the heavy rain continued into Saturday morning.

The stormy weather forced the cancellation of a gala concert in central Berlin on Friday to tie in with South Africa's hosting of the 2010 World Cup.
